Preparation method of ecological liquid fertilizer taking anaerobic fermentation liquid as basic liquid

Abstract

The invention relates to a liquid fertilizer, and specifically relates to a water soluble liquid fertilizer containing macroelements, wherein anaerobic fermentation liquid is taken as the basic liquid of the fertilizer. In the prior art, the liquid fertilizer production has the disadvantages of large water consumption, high production cost, and single functional product. In order to solve the problems mentioned above, a formula of a water soluble liquid fertilizer is designed, the fermentation liquid is taken as the basic liquid, macroelements (N, P, and K), medium elements (Mg and Ca), microelements (Zn, Fe, B, Mo, and Mn) and organic substances are compounded and added, thus the liquid fertilizer has a comprehensive nutrients and is capable of supplying sufficient nutrition, moreover, the water resource is saved, and the raw material cost is reduced. The anaerobic fermentation liquid is subjected to secondary fermentation and is fully aged so as to kill the harmful bacteria and insect eggs, while at the same time the original active substance and beneficial bacterium colonies are preserved. The fertilizer can release the soil fertility, can be easily absorbed by the plants, is capable of promoting the plant growth, has the advantages of high nutrient content, comprehensive functions, environment-friendliness, low production cost, and user-friendliness, and is capable of increasing the crop yield and improving the agricultural product quality after long term use.

Description

technical field [0001] The invention relates to a preparation method of liquid fertilizer, in particular to a process method for preparing ecological liquid fertilizer from anaerobic fermentation liquid. Background technique [0002] Liquid fertilizers are liquid products that contain one or more nutrients that crops need. Liquid fertilizers can be precisely formulated according to actual needs, and the content of various nutrients (including trace elements) can be controlled. There is no smoke and dust in the production process, and it will not cause environmental pollution and damage human health. Therefore, it is convenient to apply and is suitable for various crops, especially It is an economic plant such as fruits, vegetables, tobacco, flowers, etc. It can significantly improve the utilization rate of fertilizers, and has a good regulating effect on plant growth. More importantly, it can increase the output of plants and improve the quality of products. It is usually re...

AI Technical Summary

Problems solved by technology

Anaerobic fermented liquid is applied as a fertilizer. Although the nutrients are comprehensive, the content is low. For example, the content of organic matter, humic acid, crude fiber and dry matter is only 2%-5% of the solid content, which cannot meet the needs of crops, especially melon and fruit crops. Nutritional needs, the effect of increasing production is not obvious

In addition, after the anaerobic fermentation liquid is directly applied, it is easy to cause soil compaction, which is not conducive to the growth of plants (crops).

There are many suspended solids in the anaerobic fermentation liquid, which is turbid and opaque, and the sediment often blocks the pipes and nozzles of the liquid fertilizer application equipment, which is not conducive to farmers' use
